Hi Ken, hi all

ok, here my first report. I managed to update my sd card and merge the kobohack-j adaptions into it, but for now I have not managed to boot from the external sd card.

Here is what I did (linux commands):


Replacement of the sd card

Of course, see https://www.mobileread.com/forums/sho...d.php?t=209122

(opening the device is necessary!)

1. extract internal SD card
   
2. make image of external SD card
   dd if=/dev/sd??? of=kobo-original-sd.img
   
3. insert new SD card
   
4. copy image onto the new SD card
   dd if=kobo-original-sd.img of=/dev/sd???
   
5. resize the partition sd?3
   probably best with gparted
   
6. insert into the KOBO internal slot and reboot

Installation of kobohack-j

(opening the device is *not* necessary)

1. unpack firmware of Kobo:
   mkdir KoboOriginal-2.6.1 ; unzip -d KoboOriginal-2.6.1 kobo-update-2.6.1.zip
   
2. unpack the original KoboRoot.tgz into a separate directory
   mkdir KoboRoot ; tar -xv -C KoboRoot -f KoboOriginal-2.6.1/KoboRoot.tgz
   
3. unpack the kobohack-j-YYMMDD.zip file
   mkdir kobohack-j ; unzip -d kobohack-j kobohack-j-YYMMDD.zip
   
4. unpack the kobohack-j KoboRoot.tgz into the unpacked original KoboRoot
   tar -xv -C KoboRoot -f kobohack-j/KoboRoot.tgz
   
5. if wanted, unpack the kobohack-j KoboRoot_hack.tgz, too
   tar -xv -C KoboRoot -f kobohack-j/KoboRoot_hack.tgz
   
6. create a new KoboHack.tgz
   tar -cvzf KoboRoot.tgz -C KoboRoot .
   
7. copy new KoboRoot.tgz to KOBOeReader/.kobo/
   
8. reboot reader, it should show "Updating ..."

Booting from external sd slot

(work in progress)

I am not sure what the boot hack is doing, I though it only consists of the kernel and the boot parameters, so just using a brand new empty sd card and dd-ing it onto it should be enough. But that did not boot. The LED went blue for a moment and then nothing happened.

If anyone has an idea what the boot hack is actually doing and what is necessary to get it running, please let me know.


Thanks
